How the Eye Works
Harvard Eye Associates — 30 Years of Eye Surgery Experience!
The human eye is truly amazing. It focuses light to form images or "pictures" at the back of your eye, much like a camera. The eye instantly changes these images into electrical signals and sends them to your brain. The brain interprets the signals and you experience "seeing". The eye accommodates to changing lighting conditions and focuses rays of light originating from various distances.
Basic Structures
Cornea: This clear outer lens provides two-thirds of the focusing power of the eye. The cornea is made up of transparent tissue, which allows light to pass through. The cornea focuses the light by bending it so the light rays form an image on the retina. Since the cornea has the greatest bending (focusing) power, it is the cornea's shape that determines a great deal of quality of your vision.
Iris & Pupil: The colored part of the eye is called the iris and functions much like the iris of a camera, opening and closing, to control the amount of light entering through the pupil (that dark opening in the center the iris).
Crystalline lens: The crystalline lens is located behind the iris and provides one third of the focusing power of the eye. The crystalline lens works to further bend light rays as they pass through the eye to form an image on the retina.
Retina: Located in the lining at the back of the eye, the retina acts as an electrical system to send impulses to your brain via the optic nerve. The retina contains photoreceptor cells that collect information from light as it passes through the cornea and crystalline lens to the back of the eye. Your brain interprets the retina's electrical response into what you to experience as images.
Fovea: The focal point at the center of the retina is called the fovea. Light focused here produces the sharpest vision.
The eye focuses by bending incoming light rays to meet at a single point. Ideally this single point lands directly on the fovea, the central point of the retina. If the light rays reach this perfect placement, you experience clear, sharp images. However, if the focal point is behind the retina or in front of the retina, the image on the retina will not be fully formed and will be interpreted by your brain as blurred. This is very much like focusing a projector onto a blank movie screen. If the projection is too close or too far from the screen, the images are blurred. Set at the correct distance, you may enjoy the show!
When you have an eye examination at Harvard Eye, your eye doctor is able to determine whether you are nearsighted, farsighted, astigmatic, and/or presbyopic. Depending on your refraction, your eye doctor will discuss different treatment options with you.
